Since it was older, I decided to replace the ice maker. Bought the part and installed it. That didn't fix the problem so I defrosted freezer to make sure line wasn't frozen. That didn't fix it. I decided the only other part to replace was the ice maker controller which uses a light beam to control the ice production. I purchased the part and got it in a couple of days. Easy installation and now it is working. The videos were great and the quick delivery was appreciated.
